To evaluate the safety and efficacy of intravitreal recombinant humanized anti-VEGF monoclonal antibody in patients with visual impairment due to pmCNV


Following a 14-day maximum screening period, patients will be randomized and followed for approximately 36 weeks. Treatment visits will be scheduled in 4-week intervals. After 1 initial injection of 601 or ranibizumab (loading phase), subjects will enter an individualized flexible treatment (IFT) phase (week 4 to week 32). During the IFT phase, an assessment of disease stability will be performed at each monthly visit and subjects will receive either an injection or not. Safety and efficacy outcomes will continue to be evaluated up to a period of 36 weeks unless the patient is withdrawn or discontinues the study.

Aphakia (except IOL) or posterior capsular defect (except YAG posterior capsulotomy after intraocular lens implantation surgery)
For Any Eye
Any eye has active ocular infections (e.g. blepharitis, conjunctivitis, keratitis, scleritis, uveitis, endophthalmitis)

General Exclusion Criteria

any uncontrolled clinical problem (e.g. AIDS, active hepatitis, serious mental, neurological, cardiovascular, respiratory and other systemic diseases or malignant tumors, etc.). Malignant tumors with no metastasis or recurrence within 5 years or cancers in situ cancers are not excluded
History of system use of anti-VEGF drugs (e.g. bevacizumab) within 3 months prior to baseline
Laboratory Exclusion Criteria

Abnormal coagulation function (prothrombin time >= the upper limit of normal value for 3 seconds) and activated partial thromboplastin time >= the upper limit of normal value for 10 seconds)
